I want to compare two dates but i don't know what is the problem ?? someone help me
[HttpPost]
public JsonResult Checkdate(DateTime startdate)
{
Entities1 db = new Entities1();
bool isValid = !db.Events.ToList().Exists(p => p.StartDate.Equals(startdate, StringComparison.CurrentCultureIgnoreCase));
return Json(isValid);
}
Why wouldn't you just use the following?
db.Events.Any(p => p.StartDate == startdate);
It can be used with or without .ToList().
I do not understand what you are trying to achieve, but for date time comparisons, it is wiser to use Datetime.Compare(date1, date2) method.
like:
bool isValid = DateTime.Compare(p.StartDate, startDate) == 0;
The other answers should work but just to include this try looking for:
bool exists = false;
var event = db.Events.Where(p => p.StartDate == startdate);
if (event != null){
exists = true;
}
this way not only do you know if it's true but you have a place to hold it and see it later
you can actually return it in the Json if you'd like
